FR-E KINDLER AND BLOWTORCH.

Application iled February 3, 1922. i Serial No. 533,922.

T0 all whom t may concern.'

Be it known that I, ALFRED G. CoU'rU, a

citizen of the United States, residing at Detroit, in the county ofWayne and State of Michigan, have invented certain new and usefulImprovements in Fire Kindlers and Blowtorches, of which the following isa specification. i

The present invention relates to fire kindlers, and the main objectofthe invention is to provide an implement of this class, that is ableto start a good fire without the assistance of kindling wood, charcoalor the like. From actual tests made, it has been proved, that a goodhard-coal fire caneasily be started in about fifteen minutes and a whitehot fire in about thirty minutes, requiring only about 50 cubic feet ofgas or at the rate of about 100 cubic feet per hour, the fire kindlerproducing a blue flame about 34 inches long. i

Another advantage of this iire kindler is, that it may be applied underthe grate directly to the coal, or if ashes and cinders have collectedin the pan under the coal or in the fire boX, the lire kindler may beyinserted into the ashes without injury to it, as it is self-cleaning andno ashes can Vclog the orifices.

Another object of the invention is to'construct the device in such amanner, that it may be used as a blow torch for welding or soldering.All that is necessary in that case, is to remove the burner and therebyexpose the gas jet nozzle, which will produce in this case a blue flameabout five inches long with the same rate of consumption of gas.

Still another object is to provide an implement of a convenient size,one part thereof forming a handle of suiiicient length to prevent theburning of the operators hand, and which will be very simple, so that itmay be manufactured cheaply and those parts, which are apt to wear, maybe easily replaced at a small cost.

In the accompanying drawings one embodiment of the invention isillustrated; and

Figure 1 shows the iire kindler in top plan view partly in section;

Figure 2 is also a top plan view partly in section of a double-burnerfire kindler;

Figure 3 is a transverse section along line 3-3 of Figure 1; and

y.Figure 4 is another transverse section, along line 4-4 of the sameFigure.

The fire kindler consists of a tubular burner `10 which is closed at itsfree end by a plug 11 preferably threaded into the tubular burner.. Onthe upper side of the burner 10 is provided a number of lighter holes 12which are preferably arranged in three rows, a central row 13 of aboutsix uniformly spaced holes situated in the vertical longi- Y tudinalplane of the tube and two parallel side rows 14 which are situated inplanesfin- 4clined about 22o to the vertical plane as best seen inFigure 4. By this arrangement a long fan shaped flame will be produced,which with ordinary gaspressure projects about 34 inches above theburner, this position of the holes and the direction of the flame hasbeen experimented upon and proved to be the most desirable.

The inner end 15- of the burner 10 is threaded into a sleeve 16 which isprovided with a number of air orifices 17, four being y shown in Figure3, arranged in the same 'transverse plane of the sleeve'and spaced 90apart. y The inner end of the sleeve 16 is also threaded and engagestheouter` end 19k of the gas pipe 18, sufficient length of thread beingprovided so that the sleeve 16 may be screwed in orout on the end of thepipe for properly locating the orifices 17 with relation thereto. Inthis end 19 of the gas rpipe 18is inserted a nozzle 2O taperingoutwardly and provided with a central aperture 21v through which the gasis fedr into the sleeve 16 and burner 10. This nozzle actsas injector todraw atmospheric air through the orifice 17 of the sleeve 16 and the inand out adjustment of the sleeve 16 on the end 19 provides means forproperly adjusting the fuel mixture of gas and air before it reaches thelighter holes 12 in the burner.

At the inner end 22 of the gas pipe 18 is attached a gas cock fitting 23for regulating the intake and flow of gas from a flexible gas hose 24secured on the fitting 23.

At times it might be desirable to supply two or more burners forlighting a lire and in that case a constructionv like the one shown inFigure 2 is provided which has all theV a cock fitting 23 adapted toengage with the HeXible hose 24. A nozzle 2O is here inserted in each ofthe short pipes 25 and the free end of each burner has a plug 11 asalready described. The use of the burner is as follows. The gas pipe 18serves as a handle and has sutiicient length to prevent the burning ofthe operators hand and by means of this handle the burner is insertedbeneath the fire boX or in the ashes therein after the gas cock has beenopened and the fuel mixture has been ignited in the burner 10. rlhepressure of the fuel mixture, when emanating from the holes 12 issufficient to prevent any clogging of the holes even if the ashes aretightly packed.

By removing the burner 10 with the sleeve 16 the nozzle 21 will beexposed and the device may then be used as a blow torch, when a flameabout live inches long will be produced at the nozzle.

Instead of adjusting the position of the airV inlet orices 17 withrelation to the aperture 21 by turning the sleeve 16 on the end 19 ofthe gas Apipe 18, the adjustment may be made by pushing the nozzle 20further into the pipe.

Having thus described the invention what is claimed as new is:

1. A fire kindler comprising a gas'supply pipe constituting a handle, anozzle in the end of said pipe having a discharge orifice axially alinedwith the pipe, and a burner tube carried by the gas supply pipe anddetachably secured to the end of the pipe about the nozzle and havinglateral air inlet openings through its wall adjacent the end of thenozzle.

2. A lire kindler comprising a gas supply pipe constituting a handle, anozzle lin the Yend of the pipe having a discharge orifice alinedaxially with the pipe, and a burner tube carriedby and adjustablylongitudif nally on the end of the pipe about the nozzle and havinglateral air inlet openings through its wall adjacent the end of thenozzle.

3. A fire kindler comprising a gas supply pipe constituting a handle, anozzle inthe end of said pipe having a discharge orifice in its end, aburner tube,a cylindrical coupling sleeve having one end secureddirectly to and encircling the end of the burner tube and its oppositeend secured directly upon and longitudinally adjustable of the gassupply pipe and providedV with lateral air inlet openings through itswall adjacent the end of the nozzle, and a cut-off valve in the gassupply pipe at a point remote from the nozzle and the coupling sleeve.

a. A portable lire kindler comprising a gas supply pipe constituting ahandle, an injector nozzle having adjustable sliding engagement in theforward end of said pipe and provided with a central discharge oriiice,a burner tube in aXial alinement with said supply pipe and saiddischarge orifice, a cylindrical coupling sleeve having one end secureddirectly to and encircling the end of the burner and its opposite endthreaded upon said gas supply pipe and provided With radial air inletapertures through its wall, the turning of said coupling sleeve thuspermitting adjustment of the position of said air inlet apertures inrelation to said discharge orifice, and the sliding of said injectornozzle providing additional adjustment of said orifice and apertures.

ln testimony whereof I aix my signa ture.
